Abstract/ Executive Summary:

An experiment was conducted at the Fruit Research Farm of Horticulture Research Centre (HRC), BARI, Joydebpur, Gazipur during 2018-19 to study the performance of in-situ grafted plant on growth and yield of jackfruit. Three germplasm (BARI Kanthal-1, AH Joy-099 and AH Joy-115) were tested against seeded jackfruit plant. The experiment was laid out in the randomized complete block design (RCBD) with 4 replications. In situ grafting of 3 germplasm were done in February 2008. Planting distance was maintained 5 m x 5 m. The highest plant height was recorded in seeded jackfruit plant (7.2 m) closely followed by in-situ grafted BARI Kanthal-1 (6.90 m). The highest base girth was noted in seeded jackfruit germplasm (100 cm) followed by in-situ grafted BARI Kanthal-1 (91 cm) and the lowest base girth was noted in AH Joy-115 (73 cm). At the age of 12 years, seeded jackfruit germplasm produced the highest number of fruits (21) and the lowest fruits were recorded in T₃ and T₄which was 9. The individual fruit weight differed significantly among the treatments. The highest fruit weight was resulted in T₃ (10.60 kg) followed by T₂ (10.50 kg). But they were statically at par. The lowest individual fruit weight was recorded in T₁ (5.8 kg). The weight of fruit might be differed due to its genetical make up. The highest fruit yield per plant was found in T₂i.e. BARI Kantha-1 (136.50 kg) followed by T₁ (123.48 kg). The lowest fruit yield per plant was found in T₄ (64.80 kg). With the increase of base girth, the number of fruits per plant increased. The highest base girth and number of fruits per plant were observed in T₁.

Commodity: Jackfruit

Objectives:

To observe the performance of in-situ grafted plants in respect of growth, yield and quality of jackfruit.

Methodology:

An experiment was conducted at the Fruit Research Farm of Horticulture Research Centre (HRC), BARI, Joydebpur, Gazipur during 2018-19 to study the performance of in-situ grafted jackfruit plant on growth and yield of jackfruit. There were 4 treatments, viz. Seeded jackfruit plant (control), Grafted plant of BARI Kanthal-1, Grafted plant of AH Joy-099 and grafted plant of AH Joy-115. The experiment was laid out in the randomized complete block design (RCBD) with 4 replications. Seeds and scions were collected from respective germplasm (BARI Kanthal-1 from Akbarpur, AH Joy-099 from Fruit Research Farm, Joydebpur and AH Joy-115 from Mirzapur, Gazipur). Ten seeds were planted in a pit in the month of June, 2007. Seedlings were raised as rootstock in the experimental plot. Scions of respective germplasm grafted onto each seedling and finally one graft was allowed to grow. Vineer grafting was done in the month of February, 2008. Grafts were immediately covered with polyethylene to protect from the lower temperature in the field condition. Plant to plant distance was maintained as 5 m x 5 m. Dormant shoots of the selected germplasm were collected and used as scions. The length of scions was about 6-8 cm in length. Data on growth and development were collected every year and analyzed statistically. The mean separation was done by DMRT at 0.05 levels.
